(UNDATED) - NOAA weather radio covering a large portion of metro Indianapolis is back on the air.

An accident Monday night knocked out power to the transmitter for NOAA weather radio station KEC-74 located on Post Road on the eastside of Indianapolis.

"A dump truck was knocked into some power lines in the area, knocking down the power lines," said Dan McCarthy, meteorologist in charge with the National Weather Service in Indy.

After initially expecting the signal from NOAA weather radio station KEC-74 to be off as much as a week, the National Weather Service said Tuesday afternoon that power had been restored to the station's transmitter on Post Road on the eastside of Indy. The station was knocked off the air Monday night. "A dump truck was knocked into some power lines in the area, knocking down the power lines," said Dan McCarthy, meteorologist in charge with the National Weather Service in Indy.

The signal is one of several signals in Central Indiana that NOAA uses to send out alerts for severe weather, as well as Amber alerts for missing children. Most weather radios pick up multiple station signals, and the weather service would have still able to send alert information to send alert information to WIBC and other media outlets for broadcast. You can also access information directly from NOAA through several online and mobile device apps. "It comes out of what we call the family of services, which receives all of our products and then distributes them to the various outlets," McCarthy said.
